rod is moved to shift the belt over to the loose pulley, or disconnect the clutch if thelatter is used. Simultaneous with this operation,it is desirous to, break the electric ried by the shipper,

of the circuit which is accomplished by opening switch 23. To effect this, an arm 34: vis

yfixed on the shipper rodhaving a pin and slot connection with an 'arm` 35 liXed on shaft 36 which carries a switcharm 37 con-A stituting the movable element of the switch 23. As the shipper rod is moved to the 1 right the switch arm is'sw'ung to break contact and consequently, vopen the circuit'.v

In operation, it will beclear that upon the breaking of a yarn` thread the corre.-

spending drop wires, which are in the nature of switches, will `close the circuit to release the shipper rod. Asv the latter is shifted by the spring;l 1l to stopl the in achine the switch 23 is also opened. After the broken yarn has been again ,connected the `operator manipulates the vlever lil tok .start the machine,

the latch l5 being engagedl with. its keeper to hold the shipper rod against the tension ofspringll.
